To get the most out of my lecture, I recommend following these three steps:

Step 1: Make sure you understand the topic and practice solving problems related to it in a separate notebook.
Step 2: Review the same topic from a textbook and highlight all the important points. Use bullet points to make things easier to remember.
Step 3: Solve past papers related to the same topics to prepare for exams. This is especially important for mathematics and other calculation-based subjects.

I suggest taking a demo class before making a decision to enroll.
